Application riled @ctober 13, 1919. Serial No. 330,425.

To aZZ whom it may concern Be it known that I, JULIUS A. DYBLIE, a citizen of the United States, residing at Joliet, in the county of ffill and State of Illinois, have invented certain new and useful Improvements in slotting-Machines for Splice-Bars of which the following is a specification.

My invention relates to improvements in slotting machines for splice bars and has particular reference to an apparatus for pushing the splice bar-into proper position under the slotting punches and holding the said her while the slotting operation takes place. Heretofore in slotting splice bars which consists in cutting recesses in the base of the splice bar within which the spikes are positioned for securing the rails to the ties, the practice has been to handle the bars with ton s and for the workmen to hold them in position with tongs while the slotting or punching takes place. The slotting operation is accomplished while the bars are hot and therefore it is diilicult to properly handle and hold them in proper position. It is necessary that these slots be properly positioned with respect to the bolt holes through the bar and through which bolts are placed, otherwise they would be rejected as unfit for use. These slotting machines run continuously and the bars have to be placed in position for slotting between the strokes of the machine and at the rate of two or three hundred bars per hour, so that it is evident with the placing of the bars by hand with tongs and holding them in position results in many imperfect bars which have to be scrapped. A very large saving has been accomplished in the making of perfect bars, where otherwise the bars would be so imperfeet they would be scrapped.

Another object of the invention is the provision of a device which will add materially to the safety of operator in handling these loars in addition to the factor of comfort also involved.

Another and further object of the invenis the provision of a device which is entirely automatic in its action and which ohrates the necessity of handling the angle or 1 e liars during one stage of the operafurther oloject of the inprovision or device of the rihed which would he simple and efhcient in operation and which can easily be attached to machines used for slotting splice bars.

My invention will be further and better understood by reference to the accompanying drawings, in which Figure l is a front view in elevation of a slotting machine showing my improvedinvention;

Fig. 2 chine;

Fig. 3 is a front view in elevation showing a modified form of my improved invention;

Fig. 4 is a side view in elevation of the machine shown in Fig. 3;

Fig. 5 is a top view of a splice bar, and

Fig. 6 is a sectional view of a splice bar on lines 5-5 of Fig. 5.

Referring now specifically to the draw ings, and particularly to Figs. 1 and 2, frame 10 is shown having a shaft 12 mounted therein, the said shaft 12 carrying a head 11 se cured to the shaft 12 and adapted to slide in the frame 10. Mounted in the rear side of the frame 10 is a shaft 13 having a belt wheel 14 mounted thereon and through which the power is transmitted to the machine. Mounted on the shaft 13 on the opposite side of the frame isa small gear wheel (not shown) which meshes with a large gear wheel 15 mounted upon the shaft 12 to which the head 11 is secured. Reciprocating eccentrics are mounted upon the shaft 12, arms 12 being provided to which bearing caps 12 are secured to provide means for reciprocating the head 11, the said arms 12 being integral with the head 11. Secured to the head 11 is pair of slotting tools 16 and 17 which are adapted to punch out the slots in the splice bars as the head. 11 of the machine descends. A table 18 having a pair of die blocks 19 and 20 secured there to in any suitable manner is provided, the said table 18 being secured to the frame 10 directly underneath the slotting tools 16 and 1'7. A. splice bar 21 is shown in position on the die blocks 19 and 9A) which are secured to the table 18. A member 22 which is secured to the tahle 18 by means of a bolt 23 serves as a guide for a push rod 24: which projects through the er 22. A sprin 25 is carried by push rod and whicn is interposed hetween the head of the push rod and the m rier 22. A pin 26 ea tends through the forward end of the push rod 24 pre' ent the spring from forcing the push rod 9 through the is a side elevation of a slotting rca- Patented June in, rear.

member 22. A lever 27 which is fulcrumed upon a pin 28 carried by a bracket 29 which is secured to the frame 10 of the machine in any approved manner, carries at its lower end a bolt 30 which has a spring' 31 interposed between the head of the bolt and the lever 27. The head of the bolt 30 abuts against the push rod 24: heretofore described. A guide 32 is provided which is secured to the frame by. means of bolts 33 and serves to hold the lower end of the lever 27 in proper position. The upper end of the lever 27 carries a roller 34: which is in frictional contact with the face of a disk 35 which is secured to the outer end of the shaft 12. The disk 35 has a cam surface, as indicated at 35, so that as the shaft 12 rotates through the action of the springs on the push rod 24 and bolt30 the roller 34 is kept in contact with the face of the disk 35. A stop 36 is secured to the table by means of the bolt 37 for the purpose of providing means against which the splice bars abut, as hereinafter described.

Referring now 5 eciiically to Figs. 3 and at in which a modi ed form of my invention is shown, I provide a lever 38 which carries the spring bolt 30 at its lower end and abuts against the push rod 24. which is carried by the holder 22 in the same manner as my preferred embodiment, as heretofore described. The lever 38' is pivotally mounted in a bracket 39 which is secured to the frame of the machine in any suitable manner. A1 pin 40 extends through the outer end of the bracket 39 and through the lever 38 so as to rovide, a pivotal mounting for the said l ever. A disk 41 is mounted upon the outer end of the shaft 12 which operates the sliding head 11 to which the slotting tools 16 and 17 are secured, the said disk 41 carrying an eccentric member which issecured to the disk 41 by means of rivets 43. ll. bell crank 44 carrying a roller d5 ada ted to contact with the cam member 42 is pivotally mounted upon a bolt 4:5 carried by a member 46 secured to the frame 10 of the machine. To the upper end of the bell crank it is secured links d8 which are connected to the upper end of the lever 33 by means of bolt 49, a bolt. 50 connecting thelink 48 and bell crank aid.

in the operation at the device a splice bar 21 is placed in position upon the table 18, the machine being in the position shown in big. 1 with the slotting cad l1 elevated. the head descend c .ng with it the slotting tools, the d a rotated so that the cam surface of a 35 pusl'ies the a mounted lever bar when eanne shown in Figs. 3 and 4 the o eration is pre-' cisely the same as that described in Figs. 1 and 2. The eccentric member 42 is so positioned that it acts upon the bell crank 44, which in turn has its motion communicated through the bolt 30 and push rod 24 so as to position the splice bar 21 into proper place where it is held'during the slotting operation.

In order that difierent length splice bars may be handled ll provide push rods of different lengths, and also the stop 36 may be adjusted to different positions, as desired.

While I have described more or less precis'ely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form so and theproportion of parts and the substi tution o equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention. 7
